%description
Similar to 'rstantools' for 'rstan', the 'instantiate' package builds
pre-compiled 'CmdStan' models into CRAN-ready statistical modeling R
packages. The models compile once during installation, the executables
live inside the file systems of their respective packages, and users have
the full power and convenience of 'cmdstanr' without any additional
compilation after package installation. This approach saves time and helps
R package developers migrate from 'rstan' to the more modern 'cmdstanr'.
Packages 'rstantools', 'cmdstanr', 'stannis', and 'stanapi' are similar
Stan clients with different objectives.
